Hoping you might be able to troubleshoot a bit here -- when we try to implement this in our game, we get a node-webkit ascii message instead of the game launching. This is with zero actual 'greenworks' code in the game (just the plug-in installed and the object created).

Note:-A completely new/blank project works fine so the computer seems okay-Going through the full game files and disabling all the custom plugins doesn't fix the problem

Currently trying to delete large blocks of code to see if we can identify anything

Do you kneed to check if an achievement has been obtained before (with something like localstorage) or is that something automatically handled by Steam/greenworks? I'm presuming you don't, and can just keep telling an achievement to activate and that it will only care the first time you do it?

Can someone list the exact steps for Mac, as it says for windows in the first post? Thanks!

Does anyone else have issues getting the Steam Overlay thing to work? I can get the achivement notification pop-up in the bottom right of the screen, but I can only see if it I do the fullscreen-blackbars setting (in which case I only see it pop-up under the game but above the blackbars.

I only see the notification window in the blackbars border area and not ontop of the game? That notification will also stay there in the blackbar forever, it won't minimize/clear.
